The Sheriff's Office and investigators from the Coroner's Office were called to the facility off U.S. 190 after the skeletal remains were found. Bones and some paperwork were found in a building that used to be a temporary coroner's office and morgue, Bonnett said.

The coroner's office took the bones and will further analyze them, he said.

Someone at the facility, now called Northlake Behavioral Health Systems, called the Sheriff's Office after finding the bones, Bonnett said.
